The drawings accompanying and forming a part of this application comprises:

Figure 1 showing a sectional view taken substantially on the line 1-1 of Figure 2 of the crusher partly along the slugger roll supporting shaft and a trunnion of the swing jaw, and

Figure 2 showing a cross-sectional view of the crusher.

The embodiment of the invention comprises a casing 3 supported by end members 4 of an open rectangular frame mounted upon piers 5. A raw material inlet is mounted on top of the casing 3, said inlet including parallel vertical side walls 6, a sloping end wall 7 and a vertical end wall 8 with the lower end portions of said walls extending into the casing, as shown in Figure 2. The material inlet is mounted near one end wall of the casing 3. A crushed material outlet 9 is supported by the bottom of the casing 3 to extend in an oblique direction from the opposite end wall of the casing below the casing and between the piers 5. A crushing chamber 10 is formed in the casing 3 by the side walls of said casing, a swing jaw 11, and a slugger roll 12.

The swing jaw 11 is arranged with a concave crushing face plate 13 removably mounted on a portion of the jaw provided with a passage 14reinforced by perforated ribs 15. The upper end of the passage 14 is arranged with a circular portion 16, as shown in Figure 2, for the mounting of hollow trunnions 17 in the opposite sides of said portion. The hollow trunnions 17 are pivoted in bearings 18 supported by side members 19 of the open rectangular frame on the opposite sides of the casing 3, as shown at the right hand side of Figure l. The passage 14 is for the flow of a suitable cooling medium, such as water, introduced into said passage through a nipple 20 mounted in an opening in a wall of the passage at the lower end thereof and the nipple 20 connected to a source of water under pressure, such as the discharge side of a water pump, not shown, through a fiexible hose 21, as shown in Figure 2. The cooling medium flows upwardly through the passage 14 into and out of the hollow trunnions 17 through a nipple 22 rotatable in the outer ends of said trunnions by a fluid tight seal 23, as shown in Figure 1. A hose, not shown, is engaged on each nipple 22 for returning the cooling medium to the intake side of the source of supply. The lower portion of the crushing face plate 13 is yieldingly positioned in proximity to the slugger roll 12 by a pair of spring cages 24 supported by an end member 4 of the open rectangular frame and a rod 25 adjustably connected at one end to each spring cage with the opposite end of the rod arranged with a ball 26 mounted in a socket member 27 secured to a depending portion 28 of the swing jaw, as shown in Figure 2. The spring cages permit passage of extra hard material, such as a piece of steel, between the swing jaw 11 and slugger roll 12 by allowing the swing jaw to move away from the slugger roll. The crushing face plate 13 is removably mounted in a recess in the swing jaw and the bottom edge of said plate is yieldingly urged against an end wall 29 of said recess by a lever 30 having a nose portion 31 at one end abutting the top edge of the plate 13 and pivoted near said nose portion on the jaw, as shown at 32 in Figure 2. The nose portion 31 is yieldingly urged against the plate 13 by a spring 33 compressed between the opposite end portion of the lever 30 and a lug 34 extended from the circular portion 16. The spring 33 is retained in position by an adjustable bolt 35 extended through the spring and retained in lever 30 and lug 34, as shown in Figure -2.

The upper end of the crushing jaw plate 13 is adjacent to the lower end of the sloping end wall 7 of the material inlet so that the material will be guided toward the slugger roll and prevent spinning of the slugger roll. The slugger roll 12 comprises an annular hub portion 36 and a plurality of segments 37 of U-shape in crosssection, as shown in Figure 1, having teeth 38 integral with said segments. The segments 37 are secured to the hub portion 36 by keys 39. The slugger roll is supported by and secured to an enlarged center portion 40 of a tubular shaft 41 rotatably supported between the center portion 40 and the opposite ends in circular bearings, each bearing comprising a bearing sleeve 42 and a housing 43 having annular ribs 44 and an annular portion 45 supporting the bearing sleeve 42. The circumference of the bearing sleeve 42 is arranged with annular lubricant grooves 46. Each bearing is supported in a lubricant containing housing 47 having an annular rib 48 and a sleeve 49 engaging the bearing housing 43, as shown in Figure 1. The lubricant containing housings 47 are mounted on side members 19 of the open frame. The lubricant is delivered to the housings 47 and bearings through pipe 50 leading to the bottom of the annular portion 45 and sprayed over the bearing through a perforated pipe 51 extending transversely of the upper portion of the bearing housing 43 through ribs 44, as shown in Figure 1. The lubricant is returned to the source of supply through a pipe partially shown at 52 in Figure 1. An annular gland 53 is secured on the shaft 41 to abut the outer side of each bearing. The lubricant is sealed in the housing 47 by gaskets 54 between the housing, shaft and gland 53. The hub portion 36 of the slugger roll is secured to the enlarged center portion 40 of the shaft 41 by a key 54'. The side walls of the casing 3 are provided with openings 55 for the passage of the shaft 41 transversely through the casing and said openings are sealed by annular cap members 56 encircling the shaft and connected 3 to the slugger roll segments 37 by pins 57. The slugger roll hub portion 36 and segments 37 and the cap members 56 are maintained in fixed position relative to each other by pins 58. I

To further reduce the temperature of the crusher when crushing heated material in addition to the passage 14 in the swing jaw 11, the shaft 41 is cooled by the flow of a cooling medium, such as Water, through an annular passage 59 in said shaft formed by a rod 60, which may be hollow as shown, supported in spaced relation to the bore of the shaft 41 by spacers 61. if the rod 60 is hollow the ends thereof are closed as shown at 62 in Figure 1. The opposite ends of the rod 60 are spaced inwardly from the ends of'the shaft 41 to form circular chambers 63. The cooling medium is delivered to one of said circular chambers 63 through a nipple 64 attached to the adjacent end of the shaft 41. The cooling medium flows from said chamber 63 through the annular passage 59 to the other circular chamber 63 and an outlet nipple 65 attached to the opposite end of the shaft 41. The nipple 65 is connected to a flexible hose 66 for returning the cooling medium to the source of supply.

To still further reduce the temperature of the crusher, a flow of cooling medium, such as air, is forced over the teeth 38 of the slugger roll through an arcuate passage 67 formed by the slugger roll and a curved wall 68 mounted in the casing 3, as shown in Figure 2. The cooling medium is delivered to the lower end of the passage 67 by a spout 69 mounted in the casing 3 and having an inlet portion 70 extending exteriorly of the casing 3 for connection with the outlet of a source of supply of said cooling medium, not shown. The outlet of the passage 67 is formed by a casing 71 mounted on the exterior of the vertical end wall 8 of the material inlet. The cooling medium is discharged from the casing 71 through an outlet 72 connected to the inlet of the source of supply.

To reduce the amount of power required to rotate the slugger roll 12, ily-wheels 73 and 74 are secured to the opposite end portions of the shaft 41 extending from the bearings 42-46, whereby kinetic energy is created. The

fly-wheel 73 is connected by a belt 75 to an electric on an end portion of the shaft, a slugger roll secured on the shaft within the crushing chamber, a swing jaw pivotally mounted at the upper end within the casing and on one side of the shaft, a spring cage mounted on the frame and exteriorly of and on each side of the casing, and a rod secured at one end in each spring cage with the opposite end having a ball and socket connection with the lower end of the swing jaw exteriorly of the casing.
